Answer:
y=a(x-p)(x-q)
y=a(x+2+√2)(x+2-√2)
passing through point (-1,1)
substitute
1=a(-1+2+√2)(-1+2-√2)
1=a(1+√2)(1-√2)
1=a(1-2)
1=a(-1)
a=1/(-1)
a=-1
y=-(x+[2+√2])(x+[2-√2])
y=-(x2+4x+2)

Answer:
-105 ft
Step-by-step explanation:
His elevation after 5 minutes is -45 ft (-12*5)
= -45ft - 60ft
= -105 ft
Answer:
B
Step-by-step explanation:
this is because -300 × 4.5 = is simply -1350
(25/100)*56 = (x/100)*42
14 = (21/50)x
x = 33.333333
Answer:
Lines 2 and 4 are perpendicular
Step-by-step explanation:
Line 2: 4y=3x-4
y=3/4x - 1
Line 4: 4x+3y=-6
3y=-6-4x
y=-2 - 4/3x
The two lines are perpendicular since -4/3= - (inverse of 3/4)
